Build your own yubikey - please don't expect too much because of the catchy
title. In this workshoup you will not be able to build a fully fledged yubikey
with tamperproof memory and a real smartcard and all that stuff. But you will
be able to build your own two-factor solution with a little USB-stick.

We ordered 100+ digistumps (small USB-Sticks with a programmable
microcontroller on it) and we have at least two firmwares ready to flash
(static-password and HOTP). In addition to that we have 3D-printed cases that
you can use as a surrounding for the digistump. The cases have a little hole at
the end so you can attach them easily to your keychain.

The static password-firmware can be used to store any password or key-sequence
you might need often.

The HTOP-firmware is able to store a secret which is used to derive HOTP-Tokens
from. With that you can, for example, unlock your KeePass. The HOTP-firmware
has been developed by some guys from the labor, bochum originally.

Feel free to join us, alter the firmware, the cases and build your own yubikey.
